Fluid & Electrolytes

Fluid and electrolytes Fluid from ICF-ECF dehydration from ECF-ICF = swelling third spacing loss of ECF into a space that does contribute to equilibrium between the ICF and the RCF. -accumulates w/in membrane bound spales pentonial cavity and pleural space ex: asutes, Pleural effusion, pericardial effusion, anguedema tearly 8/s of third spacing = decrease in urine output despite adegnate fluid intake - others/s: tachycardia, B/P, decreased central venons Pressure, edema, body Wt, Imbalances in fluid intake and output
